To all whom 1' tmay concern:

Be it known'that I, Soomvrns 'Knars a" subjectbfthe'King of GreatBritain, resid ingi'at Leicester, Leicestershire, England, haveinventedcertain Improvements in Dieing-Out' Machines, of which the followingdescription, in connection with the accompanying'drawings, is aspecification, like reference characters'on the drawings indi-'catinglike parts in the several figures.

Tlils invention relates to dieing out machines and more particularly tomachines intended foruse in dieingout' thin sheet material, such asparts of uppers for boots and slices.

Someofthe objects of the invention are to provide'a dieingout' machinewhich shall be quick in operation andat the'same time shall be'soconstructed that excessive pressure will notice imparted to th'edie in adieing out operation; to provide a machine of an improved constructionadapted to insure'that but a single blow will be'applie'd to the'cutting die'when the machine'is started; and to provide a machine that maybe used with greater ease and convenience by the operator than machinesheretofore employed.

To these ends the invention consists in the features and combinationsofparts hereinafter described and referred to in the appended claims.

In the drawings,Figure 1 is a view in side elevation of a machineconstituting one embodimentof the present invention; Fig. 2 is a view inperspective with parts in section of the upper portion of. the machineshown in Fig, 1; Fig. 3 is a view in vertical section of a portion ofthemachine shown in Fig. 1; F ig.4is a view in perspective of partsshowing in a dismembered relation parts illustrated in, Fig. 3; Fi 5 isa view in front elevation with parts in vertical section of the poweractuated means hereinafter referred to and'parts cooperating therewith;Figs. 6 and 7 are views similar to Fig. 5 showing the parts in differentpositions.

Referring to the drawings, the reference numeral 1 indicates a frameupon which the parts hereinafter described are mounted. The frame 1 isprovided with a vertical web 4 and-a horizontal web 6 to the faces ofwhich is secured a bracket 8. The bracket 8 carries at its forward end awooden block 10 which constitutes a. cutting bed. The block 10 restsupon a base 12, said base having a depending. convex extension 14 whichrests in a concave seat formed'in the upper face of the bracket 8. Thebase 12 is also provided with :1. depending stud 16' which extendsthrough an aperture formed in a web 18 upon the bracket. The lower endof the stud 16 is threaded to receive clampi' g. devices 20 whereby thebase 12 may lie clamped upon the concave seat in the bracket 8. The base12, which is of rectangular shape in plan, is provided at each cornerwith a vertical web 22 extending diagonally of 'the base, and each web22 is connected to the bracketS by. bolts 2-1-- which are constructedfor adjustment in length. It will be seen that by manipulating the bolts24: the base 12 and cuttingbed 10 may be adjusted'to bring the uppersurface of the bed into a parallel relation with the lower'face of thepresser member hereinafter described.

The bracket 8 is provided at its rear end with a vertical bore of twodiameters, as shown in" Fig. 3. In the upper enlarged portion of thisbore is received the-lower end of a tubular shaft 26, upon the upper endofwhich is secured a presser member 28'projecting forwardly therefrom.In the lower portion of the vertical bore in the bracket 8 is arranged acoiled spring'30. The'upper end of the spring 30 transmits pressure tothe tubular shaft 26 through a cap'plate 32 which is arranged within thelower portion of the shaft 26 and rests against a shoulder formed on theinterior thereof? The lower end of the spring 30is engaged by a bottomplate 34 which rests upon the top of a plug 36 screwed into the lowerend of the vertical bore in the bracket 8. Secured to the top plate 32and passing centrally through the coil spring 30 is a rod 38, the lowerend of which extends through a central bore formed in the plug 36. This'bo-re-in the plug 36 is threaded and receives an exteriorly threadedsleeve 40 having a smooth inner surface. Upon the lower end of the rod38, which is threaded for this purpose, is arranged an adjustable stopnut 42 above which is placed one or more washers 44 of compressiblematerial, such as leather. It will be seen that upward movement of thecap-plate 32 through the action of'the spring 30 is lim ted byengagement of the stop upon the lower end of the red 38 with the lowerend ofthe sleeve 40. Variation in the position ofthe limit of upwardmoveadjustment of the sleeve 40 in the plug 36.

Within the upper end of the tubular shaft 26 is'received a plunger 46which rests u on a washer 48 supported upon a shou der formed on theinterior of the shaft 26. The plunger 46 is arranged in a verticalbearing 50 formed upon the upper portion of the frame 1 and is splinedin said hearing so that it is held from rotatory movement about alongitudinal axis and is free for vertical movement in said bearing. Itwill be seen that-the plunger 46 constitutes an upper bearing for thetubular shaft 26 so that saidshaft by its upper and lower bearings issecurely held from lateral movement.

In order that the bracket 8 may be so po- .sitioned upon the frame 1that the vertical bore therein will be in proper alinement with theupper-bearing 50 for the shaft 26, said bracket is secured to the frameby connections permitting its exact adjustment into a proper position.As shown 1n Figs. 1 and 3 the connections between said bracket and thewebs 4 and 6 upon the frame 1 comprise bolts 52, successive portions ofwhich are of different diameters and are threaded as shown in Fig. 3. Itwill be seen from this figure that by adjusting the several bolts 52 inthe bracket 8 said bracket may be adj usted relatively .to the frameinto' proper position. When a proper positionhas been secured, thebracket is clamped rigidly in position by the nuts upon the smaller endof each bolt 52.

In the upper end of the frame 1 is formed a horizontal bearing 54 inwhich is received a shaft 55 upon the rear end of which is arranged aloose pulley 56 and a fast pulley 58, a fly wheel 60 being formedintegrally with the fast pulley 58. A belt shifter 62 is shown fortransferring a driving belt from one pulley to the other. Upon theforward end of the driving shaft is arranged an eccentric pin 64 whichconstitutes a means for imparting a vertical reciprocatory movement toan eccentric sleeve 66 suspended upon the pin 64 and provided with adepending stem in which is reinovably secured a driving rod 68 by meansof a set screw 70. The lower end of the driving rod 68 is receivedwithin a cavity formed in the upper end of the plunger 46. \Vithin theplunger 46 is arranged a contact piece forming a shoulder 72 engaged bythe lower end of the driving rod 68 in the active operation of themachine. As will appear from Figs. 2 and 5, upon the right-hand side ofthe shoulder 72 is provided a space in which the driving rod 68 may movevertically without imparting movement to the plunger 46. The driving rod68 is held in its inoperative position by a spring 74 which presses therod against the right-hand side of the inner wall of the plunger 46, aswill appear from Fig. 5.

' which the a manually operated lever 80 pivoted at 81.

upon the frame 1 for movement about a horizontal axis. Upon the lowerend of the lever 76 is pivotally mounted a dog 82 which is maintainednormally in the position shown in Fig. 5 by a stop pin 84 against dog isheld by gravity. Arranged in a socket in the right-hand side of theplunger 46 in Fig. 5 is a vertical finger 86 which is held in saidsocket by a pin 88 and \IS pressed against the wall of the bearing 50 bya spring 90. The socket in which the finger 86 is received is so formedthat said finger may be moved laterally by the lever 76 as indicated inFig. 6. The upper end of the finger 86 is rounded off upon the sideadjacent to the finger 82. The hand lever is maintained normally in theposition shown.

in Fig. 5 by a spring 92 which holds the lever against a stop 94 uponthe frame 1..

It will be understood that inthe operation of the machine the drivingrod 68 is in continual reciprocation. To efiect an acting stroke of thepresser'member 28 the hand lever 80 is depressed, moving the lower endof the lever 76 to the left in Fig. 5 and pressing the driving rod 68into position over the shoulder 72, through the dog 82 and the laterallymovable finger 86. In the descent of the driving rod 68 the plunger 46will be depressed and the finger 86 will be drawn down with it. In thelower part of the downward movement of the plunger 46 the finger 86 willbe drawn below the end of the dog 82 and will be moved to the right inFig. 6 beneath said dog by the spring 90. The rounded upper end of thefinger 86 facilitates the' movement of said finger beneath the inner endof the dog 82. In the upward movement of the plunger 46 the dog 82 willbe turned upon its pivot by the finger 86 into a position wherein it isineffective to transmit lateral pressure to the driving rod 68, as shownin Fig. 1. The driving rod 68 is then free to be moved into itsinoperative'position at the close of the upward movement of the pressermember. The movement of the presser member is thus restricted to asingle reciprocation whether or not the operator at once releases thehand lever 80 after depressing it.

The spring 30 is so arranged that it not only imparts vertical movementto the tubular shaft 26 but also imparts a rotatory movement thereto..To this end the cap plate 32 is held from turning movement in its seatin the lower end ofthe tubular shaft 26 by means of pins 96, upon saidseat, entering recesses in the face of the cap plate 32. The upper endof the spring 30 is rigidly held in fixed relation tothe cap plate 32 bya screw 98, enteringthe stem of said cap plate and arranged in a recess100 formed in a coilof the spring 30. The bottom plate 34c is similarlyheld in fixed relation to the bottom end of the spring 30 by a screw 102arranged in a recess 10st in a lower coil of the spring. The bottomplate 34: is held from turning movement relatively to the plug 36 byrods 106 projecting from said plug through passages 108 formed in thebottom plate 3%. The plug 36 is held from turning movement in itsbearing in the bracket 8 by a set screw 110 arranged in the bracket 8 inposition to be forced against the side of the plug 36. It will be seenthat by adjusting the plug 36 in its bearing the spring may be placedunder such tension that the shaft 26 may be held normally in a )ositionadapted to bring the presscr member at a certain part of the range of is lateral movement, for example in a position atone side of the centralportion of the cutting bed.

The presser member 28 is provided with a handle 112 upon its forward endfor moving; it into a desired position over the cutting bed. The loweror acting face of the presscr member is formed by a plate 114 which maybe adjusted vertically upon the presscr member by an adjusting screw116, as shown in Fig. 1.

In the use of the machine shown, a cutting, die having been placed indesired position upon a skin supported by the cutting bed 10, thepresser member 3% is swung by the operator into position above the dieagainst the resistance of the spring 30. It will be found convenient toso adjust the spring 30 that the presser member is normally maintainedthereby at the side of the cutting bed upon the left of the operator.The presser member 28 having been brought into proper position over thedie and held there by one hand, the hand lever 80 is depressed by theother hand to bring into operation the power actuated means fordepressing the presser member. The driving rod 68 is thus brought overthe seat 72 in the plunger 46. In the next descent of the driving rod,which is in continual reciprm cation, the shaft 26 and presser member 28are depressed against the resistance of the spring 30. It will beobserved that the downward movement of the presser member is opposed bya progressively increasing resistance of the spring 30. The momentum ofthe power actuated parts of the machine in the downward movement of thepresser member is thus gradually diminished and is a minimum at thelimit of the downward movement of the presser member. The movementimparted to the presscr member is thus such that an excessive pressureupon the die does not occur. In the upward ncrement of the driving rod68, the shaft 26 and plunger 416 are raised by the spring 30, followingup the movement of the driving rod. In this portion of the operation ofthe machine the movement of the power actuated par-ts is accelerated bythe expansion of the spring 30. In the rise of-the plunger 46, thefinger 86 carried thereby, which in the downward movement of the plungerhas moved into position below the dog 82, raises said dog into itsinoperative position shown in Fig. 'i. As soon as the presser memberreaches the limit of its upward movement the driving rod 68 moves out ofcontact with the seat 72, and said drivin rod and the eccentric sleeve'66 are move by the spring T l into inoperative position wherein thedriving rod moves idly within the plunger 16. The dog 82 is maintainedin the position shown in Fig. 7 until the hand lever 80 is released bythe operator. when the parts return to the position shown in Fig. 5.After a dieing out operation has been completed, the presser member 28is released by the operator and allowed to be moved to one side of thecutting bed by the spring 30. It will be observed that during theoperation of the machine both hands of an operator are so occupied thathe is prevented from inter-posing either of them in the path of any ofthe power actuated parts. As will be apparent from Fig. 1 the hand lever80 is arranged at such a distance from the handle 112 upon the pressermember. that an operator is unable to manipulate both simultaneouslywith a single hand.

It will be observed that in the machine herein shown the means foryieldingly sustaining the presser member serves also as a mean formoving the prcsser member over the face of the cutting bed. It will beobviOuS, however, that separate and independ ent means for performingthese two functions may be provided without departing from the presentinvention.

By adjustment of the sleeve 40 in the plug 36 the normal tension of thespring 30 tending to raise the presser member may be varied. It will beobserved that this feature permits the resistance oflcred to the poweractuated means in its acting stroke to be varied and thus made of anamount suitable to secure the best results. For example, if the sleeve40 is adjusted to draw down the cap plate 32 and apply an increasedtension to the spring 30, the normal elevation of the plunger 46 andseat 72 is lowered so that movement is imparted to said plunger by thedriving rod 68 during a smaller proportion of the acting stroke of thedriving rod. The total resistance to the movement of the power actuatedparts in the acting stroke of the driving rod is thereby reduced. Theamount of movement imparted to the presser member is also reduced.

The arrangement of the plate 114 upon lit 9&1.

the presser member for vertical adjustment permits variation in heightof the cutting bed or of the die to be accommodated. It will be obviousthat the construction shown whereby the plate 114: is verticallyadjusted permits variation in the limit of downward movement of theacting face of the presser member.

It may be observed that variation in the amount of movement imparted tothe presser member could be secured by varying the eflective length ofthe driving rod 68, asby adjusting it vertically in the eccentric sleevein which it is carried. Such an arrangement would also permit the amountof resistance offered to the power actuated parts in the acting strokeof the machine to be varied. It will be understood that this arrangementfalls within the scope of the present invention. It is desired to coverherein any construction or'arrangement -wherein the downward movement ofthe presser member effected by power 'actuated means is opposed by aresistance which may be varied in amount.

The tension of the spring 30 tending to move the presser memberlaterally over the cutting bed may be varied by adjustment of the plug36. It will be understood that such adjustment may be found desirable inorder to give the presser member a normal position best suited to theconvenience of the operator. that tension tending to move the pressermember over the cutting bed may be aplied to the spring 30 in either arightiianded or a left-handed direction. It will be commonly preferred,however, to arrange the parts so that the presser member is maintainednormall in a position at the side of the cutting ed upon the left handof the operator.

It will be understood that variations in the construction andarrangement of parts from that shown may be made without departing fromthe present invention. It will be also understood that features of theinvention may be employed in relations different from that shown andthat all of the features above referred to need not be included in amachine embodying the present invention: The machine herein illustratedas an embodiment of the invention is shown by way of example and not byway of limitat-ion.
